[SPARK-23209][core] Allow credential manager to work when Hive not
available.
The JVM seems to be doing early binding of classes that the Hive provider
depends on, causing an error to be thrown before it was caught by the code
in the class.
The fix wraps the creation of the provider in a try..catch so that
the provider can be ignored when dependencies are missing.
Added a unit test (which fails without the fix), and also tested
that getting tokens still works in a real cluster.
